Magnetic fluctuations and superconductivity in YbPd2Sn
نویسنده
چکیده
We report muon spin relaxation and inelastic neutron measurements on the Heusler system YbPd2Sn. Localised anisotropic and quasi-elastic Yb magnetic fluctuations are observed below T = 150K. Both μSR and neutron data indicate a slowing-down of the spin-fluctuations, upon lowering the temperature, similar to that observed in Kondo lattices. The temperature dependence of the quasi-elastic neutron signal is compatible with a crystal-electric field scheme having a Γ 7 ground state. The muon depolarization rate exhibits an additional contribution upon decreasing the temperature below Tc suggesting a close interplay between magnetic fluctuations and the superconducting state.

Superconductivity induced by longitudinal ferromagnetic fluctuations in UCoGe.
From detailed angle-resolved NMR and Meissner measurements on a ferromagnetic (FM) superconductor UCoGe (T(Curie)∼2.5 K and T(SC)∼0.6 K), we show that superconductivity in UCoGe is tightly coupled with longitudinal FM spin fluctuations along the c axis. We found that magnetic fields along the c axis (H∥c) strongly suppress the FM fluctuations and that the superconductivity is observed in the ...

متن کاملMagnetic Hourglass Dispersion and Its Relation to High-temperature Superconductivity in Iron- Tuned Fe 1+y Te 0.7 Se 0.3
High-temperature superconductivity remains arguably the greatest enigma of condensed matter physics. The discovery of iron-based hightemperature superconductors [1, 2] has renewed the importance of understanding superconductivity in materials susceptible to magnetic order and fluctuations. Intriguingly, they show magnetic fluctuations reminiscent of superconducting (SC) cuprates [3], including ...
متن کاملPressure induced superconductivity on the border of magnetic order in MnP.
We report the discovery of superconductivity on the border of long-range magnetic order in the itinerant-electron helimagnet MnP via the application of high pressure. Superconductivity with T(sc)≈1 K emerges and exists merely near the critical pressure P(c)≈8 GPa, where the long-range magnetic order just vanishes. The present finding makes MnP the first Mn-based superconductor. The close prox...
متن کاملSimultaneous optimization of spin fluctuations and superconductivity under pressure in an iron-based superconductor.
We present a high-pressure NMR study of the overdoped iron pnictide superconductor NaFe0.94Co0.06As. The low-energy antiferromagnetic spin fluctuations in the normal state, manifest as the Curie-Weiss upturn in the spin-lattice relaxation rate 1/(75)T1T, first increase strongly with pressure but fall again at P>Popt=2.2 GPa. Neither long-ranged magnetic order nor a structural phase transition ...
